To Set Up a Chroma Key in Advanced Mode

The UltraChrome chroma key tries to automatically adjust for the scene you are trying to chroma key.
For the best results, initialize the key first, and then identify the areas where you need to adjust the key.

Click Navigation Menu > Live Assist > ME and select the ME and key that you
want to set up.

Note: You can use the same procedure for a MiniME™.

Click Key Source and select the video signal you want to use for the
key.

Click Chroma Key.

Click Advanced.

Click the Color button for the color you want to key out.

Click Init to initialize the chroma key.

Every time the key is initialized, the switcher resets all the Chroma Key parameters to their default settings.

Click an Additive Keying button to turn it on or off.

Off — Reduces the level of detail in the edges of the chroma key as well as the overall noise
in the key image that can be the result of certain lighting conditions or high detail camera settings. This is the default
setting.

On — Include the maximum detail in the edges of the chroma key.

Use the Background Neg Hue slider to adjust the range of hues that are
included in the Background, expanding counter-clockwise around the color wheel.

Use the Background Pos Hue slider to adjust the range of hues that are
included in the Background, expanding clockwise around the color wheel.

Use the Background Sat slider to adjust the saturation range of the
background color.

Increasing the saturation range value includes a wider range of saturation values to be included in the
background.

Decreasing the saturation range value includes a narrower range of saturation values to be included in the
background.

Use the Edge Softness slider to add or remove edge softening of the
foreground image and alpha channel.

Increasing the softness value increases the amount of softness applied to the foreground edges and alpha
channel.

Decreasing the softness value decreases the amount of softness applied to the foreground edges and alpha
channel.

Decreasing the clip value includes higher-saturated colors in spill suppress correction. If your foreground image
contains bright-colored areas that are suffering from background spill, decrease the clip value to have it
corrected.

Use the Spill Hue slider to select the central, or base, color for spill
suppress correction. If the color spill does not appear to be the same color as the background, use this control to adjust
which hue is considered to be "spilled" into the foreground.

Increasing the hue value moves counter-clockwise around the color wheel while selecting a base color.

Decreasing the hue value moves clockwise around the color wheel while selecting a base color.

Use the Spill Reject slider to include or reject adjacent hues to the
base.

Increasing the reject value increases the amount of adjacent hues that are included in spill correction.

Decreasing the reject value decreases the amount of adjacent hues that are included in spill correction.

Use the Transition Gain slider to adjust the appearance of the Transition
colors.

Increasing the gain value makes the transition area pixels more opaque.

Decreasing the gain value makes the transition area pixels more transparent.

Use the Translucency Gain slider to adjust the appearance of the
translucent colors.

Increasing the gain value causes the translucent colors to appear more opaque.

Decreasing the gain value causes the translucent colors to appear more transparent.

Use the Translucency Range slider to adjust the range of the translucent
colors.

Increasing the range value widens the translucent area by including more hues from the background range (the
lower-end of the range is defined by the shadow range you just set).

Decreasing the range value narrows the translucent area by excluding hues.
